Question

Molybdenum forms body-centered cubic crystals, and at 20 °C, the density is 10.3 g/mL. Calculate the distance between the centers of the nearest molybdenum atoms.

a) 1.67 Å
b) 2.78 Å
c) 3.50 Å
d) 4.21 Å

Answer 1

The atomic radius of molybdenum is not provided, so it is not possible to calculate the distance between the centers of the nearest molybdenum atoms in this case.

Step-by-step explanation:

The formula for calculating the distance between the centers of atoms in a body-centered cubic (BCC) structure is given by:

d = √(4 * (r1)2)

Where:
d is the distance between the centers of atoms
r1 is the atomic radius

In this case, the atomic radius of molybdenum is not provided. Therefore, it is not possible to calculate the exact value for the distance between the centers of the nearest molybdenum atoms.
